SPECIFICATION forming part of Letters Patent No. 486,666, dated November22, 1892.

Application filed February 27, 1892. I Serial No. 422,958. (No model.)

To all whom, it may concern:

Be it known that I, JOSIAH J. DEAL, a citizen of the United States, anda resident of Canton, county of Stark, State of Ohio, have invented anew and useful Improvement in Combination-Padlocks, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, making part of this specification.

Myinvention relates to an improvement in combination-padlocks; anditconsists in providing in a padlock a number of circular disks orrevolving tumblers, the periphery of which may be turned into atransverse opening in the shackle-ring and thereby lock it againstrotation, said tumblers having peripheral depressions that when broughtinto coincidence with the transverse opening in the shackle-ring willallow the shackle to be turned in the groove provided thereforin thecase to'bring the opening outside, when it may be removed from thestaple or from whatever it may have before had a locking engagement.

With these ends in view my invention relates to certain features ofconstruction and combination of parts, as will be hereinafter described,and pointed out in the claims.

Figure 1 of the accompanying drawings is a view in perspective ofa-padlock, illustrating my invention. Fig. 2 is a similar view with thecap removed, showing the tumblers in position and the side of theshackle-groove removed. Fig. 3 is a similar View of the central pin bywhich the cap is held in position and about which it rotates. Fig. 4. isa plan View comprising the tumblers 12, 13, and 14c and thespacing-washers and pin. Fig. 5 is a plan view looking into thelock-case from' above, showing one disk or tumbler in position to lockthe shackle against rotation, a portion having passed into thetransverse opening of the shackle. Fig. 6 is a perspective of theclick-spring. Fig. 7 is a similar view of the brake-spring; Fig. 8, aplan view of the inside of the cap; Fig. 9, a transverse section. Fig.10is'aview of a fragment of the lock, showing the screw by which thecenterpin is held in position.

Similar letters and numerals of reference indicate corresponding partsin all of the fig ures of the drawings.

For the purposes of this specificationlhave shown my invention asapplied to a cylindrical case, as shown in the drawings, Arepresentingthe case having an outer circular wall a, in which isprovided a central tube b, that forms a spindle 0, about which the disksor tumblers 12, 13, and 1t rotate and through which the bolt or pin dispassed by which the lid or cap B is loosely secured to the case A. ;Atone side of the case Ais provided a circular groove 6, adapted toreceive the shackle O, in which the shackle may be rotated. One side ofthe shackle is cut away to form an openingf, as shown in Figs. 2 and 5.

, Referring to Fig. 5, showing the interior of the ease with tumbler 14.in position to lock the shackle against rotation, having the pe ripheralcircle or circumference turned into the openingf in the shackle, thusforming an arc portion in the opening to engage the ends of the shackle,the tumblers 14:, 13, and 12, with the pins q, passing through apertures5 and 4 in tumblers 14 and 13, respectively, and the pin 7', passingthrough aperture 2 in tumbler 12, are placed upon the spindle c, the capB and interposed spacing-rings h also being in proper position. The pinsqandtwill now engage with each other when the cap is rotated, as will bereadily understood by those skilled in the art. \Vith the tumblers andcap so arranged the lock will open on figures 5 4 2that is, turn the capabout the central pin (1 one turn to the right, stopping with figure lat the top station, then turn on in same direction to bring the figure 5to the top, then turn to the left one round to bring figure 4t to thetop, and then turn to the right to bring figure 2 to the top, thusforming the combination of 5 4 2in which operation the depressions U arebrought to coincide, as shown in Fig. 2, the depressions forming theinner wall of the groove e in which the shackle is turned to carry theopening f out of the case for the purpose of unlocking or releasing thelook from the staple or post to which it may have been locked. The bar V(see Fig. 2) is placed over the side of the shackle and is secured tothe case by screws, as w, turned into the threaded aperture w in thecase, thus completing the groove 6. The pin d, by which the cap issecured to the case, is provided at one of its ends with projecting headm, that extends about the central aperture 01: in the cap B and over theedge thereof on the cap. At the other end of thepln is provided anannular groove 01: in which is turned the end of screw as. (See Figs. 5and 10.) The screw x has one side of the head cut away, as shown, thefiat side to rest against the side of the shackle, as shown in Fig. 10,by which the screw is held against rotation when the shackle is locked;and to turn the screw to remove the pin d,the shackle 1s unlocked andthe opening turned out to a potntthat will permit the screw-head to passtherein to turn the screw out of the groove.

To hold the tumblers in position as placed by the turning of the cap, abrake-spring F is provided, as shown, one end of which is secured to thecase, the free end to rest on the peripheral edges of the tumbler, asshown in Fig. 5. For convenience in operating the lock in the dark, aclick or counting spring T is provided of the form shown, one end bentat rlght angle with the body to drop into an aperture in the case, theother end having a bent-up portion x adapted to follow the groove 1: 1nthe under side of the cap B and to drop into the depressions of, bywhich an audible slgnal is produced to indicate the number of polntsthat have been turned to or passed the top of unlocking-station.

Having thus fully described the nature and object of my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a permutation-padlock, the combination, with the inclosing casehaving a circular shackle-groove, and a shackleadapted torotate in saidgroove a portion of said shackle being cut away to form an openingtherein, of a pinrality of disks or tumblers the peripheries of whichare cut away, forming circular depressions adapted to register with theshacklegroove, the rotatable cap, and the brakespring, substantially asdescribed.

2. The combination, in a padlock as herein described, of the case A,having a circular groove e, a central spindle o, a plurality of 45tumblers having peripheral depressions to correspond with the groove eof a rotatable cap B, adapted for engagement with the disks or tumblers12 and 13 to rotate said tumblers, and the tumbler 14 to lock or unlockthe shackle in the groove e, substantially as described.

3. The combination, in a padlock,of the case A, having a circulargroove, a central-apertured spindle, locking-tumblers to rotate aboutsaid spindle, springs T and F, cap B, pin S, screw w by which the pin issecured in position, and the shackle, substantially as described, andfor the purpose set forth.

In testimony whereof I have hereunto set 60 my hand this 23d day ofFebruary, A. D. 1892.

JOSIAH J. DEAL.
